These units are vital in analyzing heat transfer in HVAC systems, building insulation, and material testing.

How to Use This Tool?

  • Enter the value in degree Fahrenheit second/Btu (IT).
  • Select the conversion target unit: degree Fahrenheit hour/Btu (th).
  • Click convert to obtain the equivalent value.
  • Use results for HVAC, thermal modeling, or insulation assessments.

Key Features

  • Converts thermal resistance between degree Fahrenheit second/Btu (IT) and degree Fahrenheit hour/Btu (th).
  • Facilitates compatibility with heat flow rates expressed in Btu per hour.
  • Supports engineering and building insulation R-value calculations.
  • Browser-based and user-friendly interface.

Examples

  • 10 degree Fahrenheit second/Btu (IT) converts to 0.00277592 degree Fahrenheit hour/Btu (th).
  • 100 degree Fahrenheit second/Btu (IT) converts to 0.0277592 degree Fahrenheit hour/Btu (th).

Common Use Cases

  • Performing thermal calculations in HVAC and heat-exchanger modeling where power is in Btu/s.
  • Converting building insulation R-values to align with per-hour heat flow units for simulations.
  • Comparing imperial and SI thermal resistance units in engineering reports.
  • Specifying thermal resistance for components based on heat flow in Btu/h.

Tips & Best Practices

  • Ensure the heat flow units match when performing conversions to avoid errors.
  • Use this tool to convert values before inputting them into thermal simulation software.
  • Refer to the conversion factor 1 °F·s/Btu = 0.000277592 °F·h/Btu for manual calculations.
  • Combine resistance values with area data for accurate insulation R-value assessments.

Limitations

  • Units are specific to the Imperial/British system and require separate conversion when working with SI units.
  • Incorrect matching of heat flow units (Btu/s versus Btu/h) can lead to errors in calculations.
  • Conversion involves dividing by 3600, so numerical precision is important for transient simulations.

Frequently Asked Questions

What does degree Fahrenheit second/Btu (IT) measure?
It measures thermal resistance by expressing temperature difference per heat flow rate of one Btu per second.

Why convert degree Fahrenheit second/Btu (IT) to degree Fahrenheit hour/Btu (th)?
Because many HVAC and insulation calculations use heat flow expressed per hour, converting units ensures compatibility.

Can I convert these units directly to SI units?
Yes, but additional conversions are needed since the imperial units must be transformed into kelvins and watts.

Key Terminology

Degree Fahrenheit second/Btu (IT)
A thermal resistance unit relating temperature difference in °F per Btu/s of heat flow, used in Imperial system thermal calculations.
Degree Fahrenheit hour/Btu (th)
A thermal resistance unit expressing temperature difference in °F per Btu/h of heat flow, commonly used in building insulation and HVAC.
Thermal Resistance
A measure of a material's or assembly's ability to resist heat flow, quantified as temperature difference per unit heat flow rate.
